[PATCH 3/3] virLogCleanerShutdown: Don't call g_regex_unref on NULL regex

[Peter Krempa <pkrempa@xxxxxxxxxx>]

Shutdown of virtlogd prints:

  (process:54742): GLib-CRITICAL **: 11:00:40.873: g_regex_unref: assertion 'regex != NULL' failed

Use g_clear_pointer instead which prevents it in the NULL case.
